of thc amount of chlorate present. I t permits greater precision than the sodium arsenite-potassium bromat,e method. The sample of cell liquor for the sodium chlorate estimation may also serve for a total alkalinity deterniination if standard hydrochloric acid is used in the initial neutralization process..

SUMMARY
;liter corisiderahle iuvestigation, it is helieved that the most r:ipi(l, Liccurate method for the determination of sodium chlorate i n (*ellliquor produced in chlorine manufacture is t,he reduction of 11ic ctiloratc with excess ferrous mimonium sulfate in 40% Ii~-ti~~ochloric acid hy volume. Ammonium molylidate is used : j i t l i c c:ir:ily,
